First of all, some people have certain sensitivity and discrimination to the text itself. When words appear in front of him, he can accurately search the structure of words, notice simple points, and sometimes see the stress points and gravity points of words. More importantly, they can feel the beauty of words and then consciously change their fonts to make them more neat and beautiful.
Secondly, some people may be exposed to beautiful words from an early age. For example, parents, teachers or classmates can write good handwriting, which is the fastest stage for a person to learn and accept when he is young. They prefer beautiful things and learn new knowledge, so the beautiful words of people around them nourish them imperceptibly. They will also standardize their own fonts to a certain extent and consciously imitate them. Naturally, their aesthetic ability and font neatness are improved.
But what most people think of as a good word is only a visual sense judgment. Some good words just look neat and beautiful, and the distance between words is appropriate and the size is appropriate. However, it can't stand scrutiny and scrutiny. Good handwriting is not equal to good calligraphy. Characters simply pay attention to formal beauty, but calligraphy should be considered from many aspects, whether it is form, strength or even calligraphy. Therefore, the beauty and ugliness of Chinese characters are not necessarily related to whether you have studied calligraphy or not, which also explains the problem of "why you can write good words without practicing calligraphy" on the other hand.
